net: wwan: iosm: remove pointless null check
GCC 12 warns:
drivers/net/wwan/iosm/iosm_ipc_protocol_ops.c: In function ‘ipc_protocol_dl_td_process’:
drivers/net/wwan/iosm/iosm_ipc_protocol_ops.c:406:13: warning: the comparison will always evaluate as ‘true’ for the address of ‘cb’ will never be NULL [-Waddress]
406 | if (!IPC_CB(skb)) {
| ^
Indeed the check seems entirely pointless. Hopefully the other
validation checks will catch if the cb is bad, but it can't be
NULL.
